- IEEE1588 timestamping
- HW offloaded `ethdev Rx queue` to `eventdev event queue` packet injection
- Support Rx interrupt
+- Inline IPsec processing support
+- :ref:`Traffic Management API <otx2_tmapi>`
Prerequisites
-------------
With the above configuration, each send queue's decscriptor buffer count is
limited to a maximum of 64 buffers.
-- ``switch header enable`` (default ``none``)
+- ``Switch header enable`` (default ``none``)
A port can be configured to a specific switch header type by using
``switch_header`` ``devargs`` parameter.
With the above configuration, higig2 will be enabled on that port and the
traffic on this port should be higig2 traffic only. Supported switch header
- types are "higig2" and "dsa".
+ types are "higig2", "dsa" and "chlen90b".
+
+- ``RSS tag as XOR`` (default ``0``)
+
+ C0 HW revision onward, The HW gives an option to configure the RSS adder as
+
+ * ``rss_adder<7:0> = flow_tag<7:0> ^ flow_tag<15:8> ^ flow_tag<23:16> ^ flow_tag<31:24>``
+
+ * ``rss_adder<7:0> = flow_tag<7:0>``
+
+ Latter one aligns with standard NIC behavior vs former one is a legacy
+ RSS adder scheme used in OCTEON TX2 products.
+
+ By default, the driver runs in the latter mode from C0 HW revision onward.
+ Setting this flag to 1 to select the legacy mode.
+
+ For example to select the legacy mode(RSS tag adder as XOR)::
+ -w 0002:02:00.0,tag_as_xor=1
+
+- ``Max SPI for inbound inline IPsec`` (default ``1``)
+
+ Max SPI supported for inbound inline IPsec processing can be specified by
+ ``ipsec_in_max_spi`` ``devargs`` parameter.
+
+ For example::
+ -w 0002:02:00.0,ipsec_in_max_spi=128
+
+ With the above configuration, application can enable inline IPsec processing
+ on 128 SAs (SPI 0-127).
.. note::
parameters to all the PCIe devices if application requires to configure on
all the ethdev ports.

+Traffic Management API
+----------------------
+
+OCTEON TX2 PMD supports generic DPDK Traffic Management API which allows to
+configure the following features:
+
+#. Hierarchical scheduling
+#. Single rate - Two color, Two rate - Three color shaping
+
+Both DWRR and Static Priority(SP) hierarchial scheduling is supported.
+
+Every parent can have atmost 10 SP Children and unlimited DWRR children.
+
+Both PF & VF supports traffic management API with PF supporting 6 levels
+and VF supporting 5 levels of topology.
+
Limitations
-----------
~~~~~~~~~~~~~~~~~~~~~
OCTEON TX2 SDP interface support is limited to PF device, No VF support.
+Inline Protocol Processing
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+``net_octeontx2`` pmd doesn't support the following features for packets to be
+inline protocol processed.
+- TSO offload
+- VLAN/QinQ offload
+- Fragmentation
+
